Definitions

  • the present invention relates to a to-be-cooled body protection structure of a saddle-ridden vehicle, in which a to-be-cooled body requiring cooling with a travelling air is supported to a body frame including a front fork and a head pipe at a front end portion of the body frame, the front fork journaling a front wheel, the head pipe steerably supporting a steering handlebar, and a guard member straddles over a pair of left and right frame members configuring a part of the body frame, the guard member being supported to the body frame and located at a rear of the front wheel so as to protect at least a front portion of the to-be-cooled body.
  • the circular through-holes on the guard member disclosed in Japanese Patent Application Laid-open No. 2016-175488 cause travelling air for cooling an oil accumulation at the engine to flow through.
  • the through-holes are formed so as to have a diameter to the extent of blocking a passing of, for example, a stone to prevent, for example, the stone jumped up by a front wheel from hitting the engine; therefore, there is a demand that more travelling air is desired to be guided to the engine side.
  • the present invention has been made in consideration of the above-described circumstances and an object of the present invention is to provide a to-be-cooled body protection structure of a saddle-ridden vehicle that allows guiding a larger amount of travelling air to a to-be-cooled body side while protecting the to-be-cooled body from, for example, a small stone jumped up by a front wheel.

  • part of the through-holes provided on the guard member include at least one linearly extending linear edge portion and are formed into the non-circular shapes.
  • the non-circular through-holes adjacent to each other form the linear ribs between the linear edge portions facing one another. Therefore, the non-circular through-holes are approximated to one another while a strength of the guard member is secured with the linear ribs to provide the more non-circular through-holes on the guard member, ensuring increasing the opening areas. Additionally, the larger amount of travelling air can be guided to the to-be-cooled body side while the to-be-cooled body is protected from, for example, a small stone jumped up by the front wheel.
  • the non-circular through-holes are provided on the guard member such that the linear ribs are integrally continuous with other linear ribs, respectively.
  • the linear ribs are integrally continuous with the other linear ribs. This allows securing the strength of the guard member while the areas occupied by the linear ribs are decreased and the opening areas are increased.
  • the non-circular through-holes are formed into triangles each having three linear edge portions as said linear edge portion, and linear edge portions, as said linear edge portion, corresponding to long sides of the triangles of adjacent ones of the triangular through-holes are located so as to face each other.
  • the non-circular through-holes are the triangular through-holes each having the three linear edge portions.
  • the triangles are configured such that the three sides are in contact with an outer periphery of an imaginary circle corresponding to a circular through-hole blocking passing of, for example, a small stone to allow increasing the opening areas of the triangular through-holes while blocking the passing of, for example, the small stone.
  • the linear edge portions corresponding to the long sides of triangles form the linear ribs between them and face each other, respectively. This enhances an efficiency to locate the triangular through-holes and provides the more triangular through-holes on the guard member, thus ensuring further increasing the opening areas of the guard member.
  • the triangles have three apex angles, one of which is set to be an obtuse angle.
  • the linear edge portions corresponding to the long sides of the triangles can be lengthened and the opening areas of the triangular through-holes can be further increased.

  • one of the three linear edge portions of each of the selected triangular through-holes is located along the center rib linearly extending at the center portion in the vehicle width direction of the guard member. This allows enhancing an efficiency to locate the triangular through-holes while the center rib receives, for example, dirt jumped up by the front wheel to effectively block the jumping of the dirt to the to-be-cooled body side.

  • the remaining linear edge portions excluding the linear edge portions facing one another of the adjacent triangular through-holes are located along the bulge portions. Therefore, the step portions are interposed between the center portion on which the second plurality of through-holes are provided and the left and right bulge portions, and the linear edge portions of part of the triangular through-holes run along the step portions.
  • the second plurality of through-holes are located symmetrical with respect to the center rib.
  • the travelling air equally blows the entire to-be-cooled body, thereby ensuring equally cooling the entire to-be-cooled body.
